Posture-related change in frequency weightings derived from vibration power absorption of the hand-arm system
Bibliographic record
Abstract
The effects of hand-arm on the frequency weightings derived from the vibration power absorption (VPA) of the hand was examined. Five arm posture conditions that consist of two elbow postures, horizontally stretched straight and bent by 90 degrees, in combination with three forearm postures such as pronated, neutral, and supinated, are considered. The experiments were performed with twelve healthy male subjects in their twenties and a single-axis hand-arm vibration test system was used that included an electro-dynamic shaker that can generate vibrations. The vibration signal used in the experiments was a pseudo-random vibration in the frequency range of 10 Hz to 1,250 Hz with a flat power spectrum density (PSD) of 1.0. At frequencies ranging from 40 to 125 Hz, forearm pronation is statistically significant for the neutral/supinated forearm posture. Under the elbow-stretched postures, the VPA-based weighting factors were significantly lower than the ISO weighting factors at frequencies ranging from 12.5 to 1,000 Hz.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
